About this map

Tillamook State Forest and the Siuslaw National Forest dominate the mountainous interior of this region, where the Yamhill River and its various forks originate. Compiled from surveys spanning several decades, the map shows the transition from the rugged timberlands and coastal outposts like Netarts and Pacific City to the agricultural expanses of the Willamette Valley. In the west, the Three Capes Scenic Route winds along a dramatic coastline featuring Cape Lookout and Cape Kiwanda State Park.

Tracing inland along the Salmon River Highway, the landscape shifts toward established valley settlements and tribal history near the Grand Ronde Agency. Further east, the economic infrastructure of the 1970s is visible through the Southern Pacific rail lines serving agricultural hubs such as Sheridan, Amity, and Perrydale. This study documents the land before significant modern expansion, preserving the layout of rural crossroads like Broadmead and Meda alongside the early development of the McMinnville Municipal Airport.
